  1. 1. Science mapping and research evaluation : a novel methodology for creating normalized citation indicators and estimating their stability

    Författare :Cristian Colliander; Rickard Danell; Olle Persson; Jesper Schneider; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; document-document similarity; science mapping; citation analysis; citation normalization; stability analysis; citation impact; research evaluation; library and information science; biblioteks- och informationsvetenskap;

    Sammanfattning : The purpose of this thesis is to contribute to the methodology at the intersection of relational and evaluative bibliometrics. Experimental investigations are presented that address the question of how we can most successfully produce estimates of the subject similarity between documents. LÄS MER

  2. 2. Visualisation and Generalisation of 3D City Models

    Författare :Bo Mao; Yifang Ban; Lars Harrie; Monika Sester; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D city models; visualisation; generalisation; multiple representation structure; similarity evaluation; aggregation; typification; shell model; street index; texture compression; texture segmentation; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : 3D city models have been widely used in various applications such as urban planning, traffic control, disaster management etc. Efficient visualisation of 3D city models in different levels of detail (LODs) is one of the pivotal technologies to support these applications.

    Sammanfattning : This thesis focuses on the chemical concept of conjugation, i.e., electron delocalization, and the effect it has on electronic and optical properties of molecules. LÄS MER

  4. 4. Novel, yet similar: A similarity-assisted product family design approach for structural aero-engine components

    Författare :Julian Martinsson Bonde; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design support; aerospace; similarity metrics; aero-engine structures; design space exploration; engineering design;

    Sammanfattning : The aviation industry is in a state of transformation. The climate crisis has amplified the need to innovate, and consequently manufacturers in the aviation industry need to investigate new and more sustainable design concepts. LÄS MER

  5. 5. ɸ‑sensitivity : A step forward in future fuels evaluation

    Författare :Nika Alemahdi; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Equivalence ratio; ɸ‑sensitivity; Cooperative Fuel Research engine; Method development; Biofuels.;

    Sammanfattning : Internal combustion engine is a developed and established technology whichcontributes largely to the transportation of goods and people. In one hand, theburning of fossil fuels is the main reason for the combustion engines to beconsidered unsustainable while on the other hand, the combustion behaviour ofrenewable fuels is not fully understood yet.
